Selfhosting pivoting fails when using --store-certs-in-secrets
as controller-manager fails to start because of missing front-proxy CA
certificate:
unable to load client CA file: unable to load client CA file: open
/etc/kubernetes/pki/front-proxy-ca.crt: no such file or directory
Added required certificate to fix this.
This should fixkubernetes/kubeadm#1281
Selfhosting pivoting fails when using --store-certs-in-secrets

Secret name for etc/ca certifcate has been converted to conform RFC-1123 subdomain
naming conventions to prevent this TLS secret creation failure:
unable to create secret: Secret "etcd/ca" is invalid: metadata.name:
Invalid value: "etcd/ca": a DNS-1123 subdomain must consist of lower
case alphanumeric characters, '-' or '.', and must start and end with an
alphanumeric character (e.g. 'example.com', regex used for validation is
'[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')
